In the following figure, if the coordinates of P are (a, b, c), then the coordinates of A, B and C are respectively
|
(a, 0, 0), (b, 0, 0), (c, 0, 0) (a, 0, 0), (0, b, 0), (0, 0, c) (0, 0, a), (0, b, 0), (c, 0, 0) (a, b, c), (b, c, a), (c, a, b) |
(a, 0, 0), (b, 0, 0), (c, 0, 0) |
Clearly, Oa = a, OB = b and OC = c
As A, B and C lie on X-axis, Y-axis and Z-axis respectively. So, the coordinates of A, B and C are (a, 0, 0), (0, b, 0) and (0, 0, c) respectively. |
